21,000lbs was no trouble..... The '17 engine has a lot more torque than out '14 F350... This '17 gets the load rolling a lot easier....
The tongue weight was approx 2200lbs.
I'll put air bags on the truck if I find I have to use this truck for the big boats more....

Looks like dually material 😁 Nice looking rig. My 38 top gun doesn't sag my 250 with heavy tow pakage. Same as 350.
